SPECIFICATION formingpart of Letters Patent No. 251,898, dated January3, 1882.

Application filed November 2, 1880. (No model.) Patented in GermanySeptember 23, 1880, in Belgium October 12, 1880, in England Octobcr12,1850, in France October 12, 1880, in Italy October 12, 1880, in SwedenDecember 1, 1880, in Austria-Hungary December 11, 1880, and in SpainJanuary 5, i881.

To all whom it may concern:

Beit known that l, EDUARD KtiHLEmre' ofPrussia, German Empire, have invented im- 'provements in Lamp of which the following is aspecification.

The object of this invention is to furnish an im provedlamp which, maybe conveniently used in connection with a percussion lightingdevice,also as'a night-lam p, and for similar purposes. The lamp is soconstructed thatit can be instantly lightcdand used without the leastdanger. p

Theinvention consists of a lamp made of a cylindrical reservoir which isprovided with a suitable burner and charged with pieces of sponge orother porous material and a volatile hydrocarbon oil. A perforated plateor screen is interposed between the sponge and wick.

It consists, further, of the combination of the cylindrical reservoirwith a sliding sleeve and a percussion lighting device which is pivotedto the sleeve and adapted to light the burner of the lamp.

Inthe accompanying drawings, Figure 1 represents a side elevation of myimproved lamp; Fig. 2, a vertical central section of the cylindricalreservoir; Fig. 3, a horizontal section of the same; and Figs. 4, 5, and6 show respectively a vertical longitudinal section, an end view, and atop view, of alamp and its percussion device, adapted as a pocket lampand lightin g device.

Similar letters of reference indicate corresponding parts.

In the drawings, a represents the cylindrical reservoir of my improvedlamp, which is made of the size and shape of a candle and secured toabase or holder, which is in the nature of a candlestick, as shown inFig. 1. The burner dis secured on to the upper end of the reservoir aand provided with a wick-tube, cl, which extends downward into thereservoir a. The upper part of the reservoir a is separated from thelower part by a perforated plate or screen, b, above which is placedalayer of cotton waddin g in such a manner that the wick of the burner dis kept in contact therewith. The wick is raised or lowered in thewick-tube d bya spurwheel, s. The lower part of the reservoir (1, belowthe screen I), is filled with pieces of sponge danger of explosion, evenwhen handled by the most inexperienced persons.

1 The upper and lower ends of the reservoir are provided with projecting'shoulders a,which serve as stops for a sliding sleeve,f,that ispreferably guided by a ton gne-and-groove connection, la, vertically onthe reservoir The sleeve f is provided with two brackets, 3, one ofwhich is rigidly attached to the sleeve, while the other is preferablyhinged thereto at 2', as shown clearly in Fig. 3. The brackets l supporta percussion lighting device, g, which is constructed, as customary inthe well-known percussion lighting devices, with an interior tape, h,provided at regular intervals with pellets of an explosive substance.The casing of the percussion device g is pivoted to the brackets l ofthe sleeve f, so as to be swungtoward the burner, as in Fig.2,or awayfrom the same, as shown in Fig. 1. One of the brackets l is hinged tothe sleeve, so that the percussion device may be readily removed forreplenishing the tape. The shell g vibrates on a stud which is on thefixed bracket 1, and is limited in its vibration by the stud 0, whichpasses through the slots. The slide or tape-feeder-i is pivoted to stud0, and its upper end is pressed by a spring, m, against the tape. Thespring m is rigidly secured to the shell 9, and its upper end is bent,so that it serves as a hammer to strike and ignite the pellets. At a ateat is formed on the springm, which teat is arranged in such relationto a slot, t, through the feeding-slide i, that when the shell'g isdrawn back to the position shown in Fig.1the teat will ride upon theslidei above the said slot. When it is desired to light the lamp theigniter is moved to the proper height and its upper end pressed forwardtoward the wick. This allows the teat to snap into the slot t and theupper end of the spring-hammer to strike a pellet. backward movement ofthe shell 9 the slide 2' will'i'eed a pellet up to a position to bestruck by the spring-hammer.

For the purpose of lighting the lamp all that is required is to slidethe sleeve fin upward direction until stopped by the shoulder a of theburner 01, and to swing then the percussion device g toward the burner,as shown in Fig. 2, by which motion the percussion device is broughtinto operation, a pellet ignited, and thereby the lamp lighted.

The same arrangement may also be applied to a pocket lamp and lightingdevice bysimply making the reservoir of U shape, as shown in Fig. 4, andpivoting the percussion lighting deviceg to the side walls of aninclosing-casing. The burner is in this case not detachable, butstationary, and provided with a wick-regulating spur-wheel, s, at oneendand with a'removable cap at the other end, through which ihereservoir a is filled with oil. The construction of the lighting deviceis exactly the same as before described, the only difference being thatit is moved by a button which passes through a slotin the side wallot'the casing, it being taken hold of after opening a hinged cover, whichis retained in closed position by asuitable catch device, as shown inFig. 5.

The percussion lighting device g may be acted upon by a spiral or otherspring, which iscompressed when the devicegis thrown to one side, asshown in dotted lines in Fig. 4. On releasing the side button of thelighting device it is thrown by the spring toward the burner, so as toignite thereby the pellet of the tape and the lamp in a quick andreliable manner.

At every Havinglhus described my invention, I claim as new and desire tosecure by Letters Patent 1. A safety-lamp similar in form to acandlestick, composed of an elongated tubular body or reservoir adaptedto receive a verticallysliding lighting attachment, a conical burnerdetachably fastened to the upper end of said tubular body and providedwith a central wicktube, and a supporting-plate at the lower end of thebody, said body being divided below the' burner by a perforated plate orscreen into two parts, the lower part being filled with sponge or otherporous material, while the part above the screen is filled with waddingor other material, by which the oil is transmitted from the lower partto the wick, substantially as described.

2. The combination, with atubular reservoir, at, having a burner, d, andan upper shoulder or stop, a, of a sliding sleeve,f, and a percussionlighting device pivoted to the brackets of the sleeve, substantially asdescribed.

3. As an improvement in lighting devicesfor lamps, the combination, witha reservoirand burner, of an oscillating percussion lighting deviceprovided with means for automatically striking the fulminate uponapproach of the lighting device to the burnerot' the lamp, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDUARD KOHLER.
